I am new to home theater stuff and I watch mainly dvd movies. I have shortlisted Mission FS2 AV and Kef KHT 2005AV. I like the idea that the Mission can be ceiling mounted. Can I do this with the Kef without affecting its performance. Movie directors are increasingly placing effects carrying midband to the rears and since the NXT speakers are so bass light (frequency response 285Hz-20kHz), Will this affect the reproduction of 5.1 sound ?. Thanks!
